SEEDING-MACHINE.

QPEGIFICATION forming part Of Letters Patent N 0. 627,116, dated June 20, 1899.

Application filed December 16,1898. Serial No. 699,506. (No model.)

To all whom it may concern:

Be it known that I, GEORGE D. HAWORTH, of the city of Chicago and State of Illinois, have invented certain new and useful 1m provements in Planting-Machines, of which the following is a specification.

This invention in its entirety relates to d rill-planters in which disks are used to open the furrows, though some of its features are applicable to various kinds of planting-machines. It is exemplified in the structures hereinafter described and it is defined in the appended claims.

In the drawings forming part of this specification, Figure 1 is a plan of so much of a seed-drill asis needed to show the connection of my invention therewith. Fig. 2 is a crosssection through the principal member of the frame of the drill. Fig. 3 is a representation of the under side of a fragment of the bar of which the principal member of the frame is constructed. Fig. 4 is a representation of the under surface of a corner of the frame. Figs. 5, 6, and 7 are side elevations of the raising and depressing mechanism for the furrow-openers, showing the mode of operation thereof. Fig. 8 is a plan of a draft-bar for a furrow opener. Fig. 9 is a side elevation of the draft-bar. Fig. 10 is a section on line A in Fig. 8. Fig. 11 is a section on line B in Fig. 8. Fig. 12 is a section on line C in Fig. 8. Fig. 13 is a side elevation of a furrow-opening disk and the frame therefor,

showing the construction of the scraper used to clean the disk. Fig. 14 is an elevation of the disk-frame with the disk and scraper-bar removed to expose a plate used to form a side of the shank-tube, through which the seed is delivered. Fig. 15 is a section through the seedboxof the drill, illustrating the means used to support the drill-shaft and hold the sprocket-Wheel thereon in alinement with the sprocket-wheel on the main shaft. Fig. 16 is a detail of the support for the drill-shaft, the same being represented as it appears from the front of the drill.

The bar 1 1 forms the front cross-bar and the side bars of the frame. angle-iron, one member of which is horizontal and the other vertical, asfshown at Fig. 2. To make the bends at the corners of the frame, the horizontal member of the angle-iron is It is made.of-

the divergent surfaces 1" are made to abut one against the other, the salient angles defined by lines 1 and the edge of the iron are deflected sufficient to overlap, holes, as 1, are made through the overlapping portions, and rivets or the like are used to fasten snch portions together.

The-draft-bars are made of pieces of angleiron turned with the external angles upward.

The intermediate portions of the bars are left unchanged, as shown at 17 in Fig. 11. front ends are spread slightly, asshown at 17 in Fig. 10, and the rear ends are compressed, as shown at 17 in Fig. 12. The spread portion 17 is provided with rivet-holes in its edges, by means of which it is fastened to a hinge-bracket 18. The compressed portion 17 is provided with horizontal holes, by means of which it is connected with the disk-frame, and the intermediate portion 17, with its external angle upward presented, constitutes a bar particularly well able to stand the com- The.

loined stresses to which such bars are subjected.

The tube in the shank portion 10 of diskframe!) is open on the side next the disk, and the shank has pins 11 extending from its upper end toward the disk. To keep the tube of the seedbox from rubbing against the disk when it is inserted into the shank of the diskframe, a plate 12 is fastened at its upper end on pins 11 and riveted at its lower end to a convenient portion of the disk-frame, as shown. This plate forms a wall for the open side of tube 10, separating the seed-tube from the disk and controlling the discharge of the seed.

. The scrapers for the disks are each made of a strap or bar of metal, as 1?, which extends horizontally across the shank of the diskframe, then bends on itself, as shown at 14,

and extends downward and inward adjacent journaled in the frame in bearings, as 4 and 5. Arms 7 are mounted on the rock-shaft,

and suitable connections, as bars 8, extend the toe extension to a like extent.

between the arms and the furrow openers. By rocking the shaft 6', so as to raise or lower the arms 7, the furrow-openers are correspondingly elevated or depressed, and one feature of my invention is designed to provide improved means for rocking the shaft 6. To accomplish this, 1 fix an arm 39 onto the shaft, fasten a bracket onto an extension '24 of the frame, pivot a lever 26 to the bracket, and connect the front end of the lever 26 with arm 39 by means of a link 29. The pivots of these parts are so disposed and the parts are so prover 26 will tend to turn the rock-shaft, forcing it upward if the end of arm 39 is above the dead-lock-position, as shown in Fig. 5, and forcing it downward if the end of the arm is below the dead-lock position, as shown in Fig. '7. The weight of the furrow-openers may be depended on to carry the arm downward below the dead-lock; but there is something needed to assistin passing the dead-lock point in upward travel of the arm, and link 29 is extended upward and rearward, as lever 30, in such manner I hat. force applied through the lever will be exerted laterally on the link and the arm 29.

The lever 26 is fulcrumed at 28 on bracket 25, and its lift end 27 is extended forward and downward from the fulcrum. A ratchetrack 32 is supported concentric with pivot 28, partly by such pivot and partly by a bar 33, which extends forward and connects with the tongue 3 or some other available part of the frame. The lever 26 has a lateral extension that acts as a foot-rest, and it is supplied with a pawl 34 in position to engage the teeth of the ratchet-rack. The pawl has a rear ward extension, from the rear end of which projects a toe-bearing 35. A rod 36 is connected pivotally with the pawl in the rear of the pivot thereof and is extended loosely through a lug 37 on lever 26. A spring 38 is placed on rod 36 between the lug and the pawl in a manner to exert pressure toward the pivot of the pawl. The pivot of rod 36 and the bearing of the rod in lug 37 are such that when the pawl is in operative position, as shown in Figs. 5 and 7, the spring will press the detent'end of the pawl toward the ratchet-teeth, and when the toe-bearing end of the pawl is depressed to the extent illustrated in Fig, 6-the spring acts to hold the pawl out of engagement with the ratchetteeth. When the operator wants to use the pawl to lock the levers, he raises extension 35 with his toe or otherwise until the pivot I of bolt 36 swings past a rightline drawn from the pivot of the pawl to the bearing in lug 37, and when he wants the levers to move without restriction from the pawl he depresses The lever 26 is used to depress the furrowopeners and to raise them, pressure being applied downward on the foot-rest in each instance. the relative position shown in Fig. 5, down- ,W'hen the arm and the link are in ward pressure on the foot-lever tends to raise the furrow-openers and hold them raised, while when the arm and the link are as shown in Fig. 7 the same downward pressure on the foot-lever will act to depress the f u rrow-openers. When the position shown in Fig. 6 is reached in upward motion of the furrowopeners, the foot-lever becomes powerless on account of alinement of pivots, and at this juncture the hand-lever 30 is used. to carry link 29, which is an extension of the handlever, past the dead-center line. to this function of the hand-lever it is obvious that it may be used in conjunction with the foot-lever when the furrow-openers are heavy enough to require special effort to raise them or when there is difficulty in forcing the furrow-openers into the ground the required depth.

Another feature of my invention relates to means for supporting the drill-shaft and holding the sprocket-wheel thereon in operative position. Such means consist of a strap, as 40, fastened to the front of the seedbox 23 and extended downward and backward under the box, a bar 41, fastened at one end to strap 40 and having a bent extension at the other end that fastens to the seedbox-support, and a yoke 42, that is fastened to bar 41. The yoke straddles the sprocket-wheel 45 of the drill-shaft 49, and it provides bearings 43 for the laterally-projecting ends 44 of the hub of the wheel. The bearings support the shaft by supporting the wheel thereon, and the yoke holds the wheel from sidewise motion when the shaft is shifted lengthwise to regulate the discharge of the seed. The sprocket-wheel 45 is driven from sprocket-wheel 21 on shaft 20 of carrying-wheels 19 by means of chain 22, and strap 40 is provided with a tightener for the chain. The tightener consists of a slide-block 46, held adj ustably on the rear end of strap 40 by means of a set-screw 48 and a bearing-surface 47, extended laterally from the slide-block into the plane of the chain.

WVhat I claim is 1.
